Cang Hai

Cang Hai (died 218 BC) was a Qi loyalist who, in 218 BC, attempted to assassinate Emperor Qin Shi Huangdi. Cang Hai was the son of a Qi soldier, and he was left with a hatred of Qin Shi Huangdi due to his conquest of his homeland. He was approached by Zhang Liang, who believed him to be a mercenary; however, Cang Hai said that he did not kill for money, and he was instead recruited into Zhang Liang's plot when the two of them discussed Qin Shi Huangdi's tyranny. The two men attempted to ambush the Emperor of Qin near Bolangsha, with Cang Hai using a large hammer to destroy several carriages in the Emperor's convoy, intending on killing the Emperor. However, he only succeeded in killing the Emperor's uncle and several Qin soldiers, and he was killed while attempting to flee the failed ambush.
